The purpose of the invention is to expand the technological capabilities and increase productivity by combining drilling operations, making rivets, riveting and automating them in the manufacture of a package of friction and metal discs.

FIG. 1 shows the proposed device, a general view; FIG. 2 is a view A of FIG. 1 in FIG. 3 is a view B in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 is a cross-section of Mr. and Mr. FIG. G, FIG. 6 - section dd on

FIG. four; in fig. 7 — node 1 in FIG. 6 J

(detailing) J in FIG. 8 shows the execution of the punch when riveting tubular rivets J onto fit. 9 is a cross-section of a bottom of E-E in FIG. five.

The drilling-riveting device contains 2 parts package clamping mechanism 1 mounted on the base, associated with a 3-turn drive, co-located on both sides of the mechanism 2 clamping a package of parts, working actuators 4 and 5 with sockets for riveting and drilling tools installed with sequential alternation of uniformly circumference. So, drilling tools 6 of the working executive body 4 are spaced one from another at an angle of 2si. The same number of riveting tools 7 is located between the drilling tool 6, 6 degrees apart from it, the drilling tool 6 is designed as a countersink B with an axial bore 9 for removing the rivet blank and an annular protrusion 10 on the outer surface of the spline sleeve 11 mounted on a countersink 8 with the possibility of movement relative to the latter under the action of an annular power cylinder 12 due to a spline connection, spring-loaded 13 of a movable cutter 14 mounted on a sleeve 11 and connected to a shaft with an end lip 10 by means of a two-arm lever 15 and a wedge element 16. The annular power cylinder 12 is made with an annular head 17, which is U-shaped in cross section, and through bearings 18 and ring 19 interacts with

countersink 8. The movement of the splined sleeve 11 and the compression of the spring 20 is limited to two thrust bearings 21. The working actuator 5 contains a drive drilling tool 22 and a riveting tool 23. The location of the axes of the drive drilling tools 22 and riveting tools 23 is similar to the location of the axes of the drilling 6 and riveting 7 tools working actuator 4. The clamping mechanism 2 and the rotation actuator 3 are made together in the form of a rotary around its axis on the bearings 24 of the plate 25 and rotatable around its axis plates 26 associated with the cylinder 27. The plates 25 and 26 are rotated by the cylinder 28 through the stop 29 and the axis 30 mounted in the lugs of the said plates. The riveting tool 7, spring loaded 31J, contains spring-loaded spring 32, the centering rivet forming head 33, and spring 31. more rigid than spring 32. For working with tubular rivets, riveting tool: No 7 is equipped with spring loaded centering sleeve 33 ( Fig. 8). The driving drilling tool 22 is designed as a special drill 345 that simultaneously drills a hole and

5 chamfering. Axial movement of the drill bit 34 is transmitted from an annular power cylinder 35 having an annular head 36. A riveting tool 23 is similar to a riveting

.0 tool 7. In addition, the device contains riveting mechanisms 3 7,

Drilling riveting device works as follows.

 From the accumulator (not shown) the disks in the set: a friction disk, a metal disk, a second friction disk are fed into the gap formed by the rotary plates 25 and 26,

O and set on the support 29 of the actuator 3 rotation. A control device (not shown) is activated, which actuates the power cylinder 27, which moves the turntable

 26 E towards the plate 25 and clamping the package details. Next, the control device commands the working medium to flow into the rodless cavity of the annular cylinder 35, under the action of which the special drill 34 advances and drills the package of parts and chamfering, after which the command to retrace it is given. The working medium is fed into the rod cavity of the annular cylinder 35, with the special drill 34 returning to its original position, and the countersink 8 begins to countersink the chamfer. The working medium is fed into the rodless cavity of the annular power cylinder 12, under the action of which the countersink 8 extends, loosened the force on the spring 20. T1 finally puts pressure on the splined sleeve 11, which in turn extends from the working actuator 4 all the way into the thrust bearing 21. After When the slotted sleeve 11 of its extreme position, the countersink 8 continues to move and, extending out of the slotted sleeve 11, weakens the force on the double-arm lever 15, which interacts with the smaller wedge element 16 and under the action 13 ( otorrhea was compressed), the movable cutter 14 is retracted in the spline sleeve 11. On further movement in the countersink bevel formation occurs, and then applied to the rivet feeding command material (rods, tubes). The latter is fed into the axial hole of the working actuator 4 by means of a feed mechanism (not shown). The feed mechanism feeds rivet material at a strictly defined size. After the material is supplied, the working medium is supplied to the rod cavity of the annular power cylinder 12. Zenker 8 retreats to its original position, while its annular protrusion 10 interacts with the double-arm lever 15, which presses on the wedge element 16 The blade 14 is extended and the spring 20 is compressed, produced rivet blank. Upon further movement of the countersink 8, he carries along the splined sleeve 11,

and with it rivet material. A command is given to rotate the plates 25 and 26 at an angle d. The working medium is fed into the rodless cavity of the force 5 cylinder 28, rotation takes place. plates 25 and 26 at an angle ", i.e. the rivet axes are aligned with the axes of the riveting tools 7 and 23. A command for riveting is given, and a working medium is fed into the headless cavity of the power cylinders of the riveting mechanisms 37. The riveting mechanism plates 37 press on the riveting tools 7 and 23. Overcoming the force 15 of the springs 32, the riveting tools 7 and 23 are swiveled from the working actuators 4 and 5, while the spring 31 is in its unclenable state due to its high rigidity. When 20 movement of the riveting tools 7 and 23, the centering sleeves 33 move on the rivets, the springs 31 are compressed, the rivets are riveted, after which the working medium is fed into the rod cavity, the plates of the glue-. the pallet mechanisms 37 retract to their original position and under the action of springs 31 and 32 riveting tools 7 and 23 and the centering sleeves 33 3Q also retract into their initial position. Then the command is sent to the long-distance. The wide rotation of the plates 25 and 26, the rod of the force cylinder 28 of the actuator of the rotation 3 moves further, the rotation of the plates 25 and 26 takes place at an angle, and the command to unclamp is given. The working medium is fed into the rod cavity of the power cylinder 27 of the clamping mechanism 2, the rotary plate 26 moves away from the discs and expands them, while due to the displacement of the center of gravity of the disk pack, they exit the gap and slide into the container, onto the conveyor and etc. After unloading the device, a command is issued to return the actuating cylinder 28 of the actuator 3 to the initial position. The working medium is fed into the rod cavity of the power cylinder 28, the rotary plates 25 and 26 are returned
